CVE-2019-0220 – httpd: URL normalization inconsistency
https://notcve.org/view.php?id=CVE-2019-0220
A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account for duplicates in regular expressions while other aspects of the servers processing will implicitly collapse them. Se descubrió una vulnerabilidad en Apache HTTP Server 2.4.0 hasta 2.4.38. Cuando el componente del recorrido de la solicitud de la URL contiene múltiples barras diagonales consecutivas ('/'), como por ejemplo LocationMatch y RewriteRule debe tener en cuenta los duplicados en las expresiones regulares que otros aspectos del procesamiento de los servidores los colapsarán implícitamente. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00051.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00061.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00084.html http://www.openwall.com/lists/oss-security/2019/04/02/6 http://www.securityfocus.com/bid/107670 https://access.redhat.com/errata/RHSA-2019:2343 https://access.redhat.com/errata/RHSA-2019:3436 https://access.redhat.com/errata/RHSA-2019:4126 https://access.red • CWE-41: Improper Resolution of Path Equivalence CWE-706: Use of Incorrectly-Resolved Name or Reference •
CVE-2019-0211 – Apache HTTP Server Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-0211
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected. En Apache HTTP Server 2.4, versiones 2.4.17 a 2.4.38, con el evento MPM, worker o prefork, el código ejecutándose en procesos hijo (o hilos) menos privilegiados (incluyendo scripts ejecutados por un intérprete de scripts en proceso) podría ejecutar código arbitrario con los privilegios del proceso padre (normalmente root) manipulando el marcador. Los sistemas que no son Unix no se ven afectados. A flaw was found in Apache where code executing in a less-privileged child process or thread could execute arbitrary code with the privilege of the parent process (usually root). • https://www.exploit-db.com/exploits/46676 http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00051.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00061.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00084.html http://packetstormsecurity.com/files/152386/Apache-2.4.38-Root-Privilege-Escalation.html http://packetstormsecurity.com/files/152415/Slackware-Security-Advisory-httpd-Updates.html http://packetstormsecurity.com/files/152441/CARPE-DIEM-Apache-2.4.x • CWE-250: Execution with Unnecessary Privileges CWE-416: Use After Free •
CVE-2019-3836 – gnutls: invalid pointer access upon receiving async handshake messages
https://notcve.org/view.php?id=CVE-2019-3836
It was discovered in gnutls before version 3.6.7 upstream that there is an uninitialized pointer access in gnutls versions 3.6.3 or later which can be triggered by certain post-handshake messages. Se descubrió en gnutls, antes de la versión 3.6.7 upstream, que hay un acceso de puntero no inicializado en gnutls, en versiones 3.6.4 o posteriores, que puede desencadenarse por determinados mensajes "post-handshake". A flaw was found in the way gnutls handled malformed TLS 1.3 asynchronous messages. An attacker could use this flaw to crash an application compiled with gnutls via invalid pointer access. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00017.html https://access.redhat.com/errata/RHSA-2019:3600 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3836 https://gitlab.com/gnutls/gnutls/issues/704 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/A3ETBUFBB4G7AITAOUYPGXVMBGVXKUAN https://security.gentoo.org/glsa/201904-14 https://security.netapp.com/advisory/ntap-20190502-0005 https://usn.ubuntu.com/3999-1 https://access. • CWE-456: Missing Initialization of a Variable CWE-824: Access of Uninitialized Pointer •
CVE-2018-12545
https://notcve.org/view.php?id=CVE-2018-12545
In Eclipse Jetty version 9.3.x and 9.4.x, the server is vulnerable to Denial of Service conditions if a remote client sends either large SETTINGs frames container containing many settings, or many small SETTINGs frames. The vulnerability is due to the additional CPU and memory allocations required to handle changed settings. En Eclipse Jetty, en versiones 9.3.x y 9.4.x, el servidor es vulnerable a una denegación de servicio (DoS) si un cliente remoto envía frames SETTINGs bastante largos que contienen muchas opciones, o muchos frames SETTINGs pequeños. La vulnerabilidad se debe a las asignaciones adicionales de CPU y memoria necesarias para gestionar las opciones cambiadas. • https://bugs.eclipse.org/bugs/show_bug.cgi?id=538096 https://lists.apache.org/thread.html/13f5241048ec0bf966a6ddd306feaf40de5b20e1f09096b9cddeddf2%40%3Ccommits.accumulo.apache.org%3E https://lists.apache.org/thread.html/70744fe4faba8e2fa7e50a7fc794dd03cb28dad8b21e08ee59bb1606%40%3Cdevnull.infra.apache.org%3E https://lists.apache.org/thread.html/9317fd092b257a0815434b116a8af8daea6e920b6673f4fd5583d5fe%40%3Ccommits.druid.apache.org%3E https://lists.apache.org/thread.html/febc94ffec9275dcda64633e0276a1400cd318e571009e4cda9b7a79%40%3Cnotifications.accumulo.apache.org%3E https:/ • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
